Generally speaking, I think people (including myself) don’t know how to be tired.
Think about it. Do you recognise when you are weary and stop and rest?
First of all, you have to be in touch with your body and mind to notice when fatigue symptoms are arising. But often, we are out of our bodies when we are driving ourselves to get a job done. You know the drill – when you are rushing against the clock or when you try to cram just one more thing in just so you can find time to rest later.
Even when you know that you should rest, you might not because it’s not convenient. You’re out and about and there’s no place to sit down. There’s no quiet spot to meditate or do savasana.
When you finally do alight, your body might be too exhausted to let go and/or your mind too busy to still. Even a night’s sleep doesn’t give refreshment when you’re depleted. And so you start the next day with your reserve tank on low.
For my part, I get cranky when I’m tired. It’s probably a defence so no one gets too close to finding out how tired I am. Hey, I’m a yoga teacher – a fount of renewable energy. My husband, when he’s rundown, might become withdrawn, like the castle guard putting up the drawbridge. A friend of mine is prone to depression when exhausted.
It would be so much easier to do what my sensible friend Heather does each day, as do the people who live in sunny, hot climes. Take a daily siesta.
Judith Lasater, author of Relax and Renew, says that it takes courage to rest and relax. It’s means you’re going against the protestant work ethic but you’d be complying with the practical Buddhist idea:

“When you are hungry, eat. When you are thirsty, drink, and when you are tired, sleep.”
